Properties of nuclear matter are investigated in the framework ofrelativistic Brueckner-Hartree-Fock model with the latest high-precisioncharge-dependent Bonn (pvCD-Bonn) potentials, where the coupling between pionand nucleon is adopted as pseudovector form. These realistic pvCD-Bonnpotentials are renormalized to effective nucleon-nucleon ($NN$) interactions,$G$ matrices. They are obtained by solving the Blankenbecler-Sugar (BbS)equation in nuclear medium. Then, the saturation properties of symmetricnuclear matter are calculated with pvCD-Bonn A, B, C potentials. The energiesper nucleon are around $-10.72$ MeV to $-16.83$ MeV at saturation densities,$0.139$ fm$^{-3}$ to $0.192$ fm$^{-3}$ with these three potentials,respectively. It clearly demonstrates that the pseudovector coupling betweenpion and nucleon can generate reasonable saturation properties comparing withpseudoscalar coupling. Furthermore, these saturation properties have strongcorrelations with the tensor components of $NN$ potentials, i.e., the $D$-stateprobabilities of deuteron, $P_D$ to form a relativistic Coester band. Inaddition, the charge symmetry breaking (CSB) and charge independence breaking(CIB) effects are also discussed in nuclear matter from the partial wavecontributions with these high-precision charge-dependent potentials. Ingeneral, the magnitudes of CSB from the differences between $nn$ and $pp$potentials are about $0.05$ MeV, while those of CIB are around $0.35$ MeV fromthe differences between $np$ and $pp$ potentials. Finally, the equations ofstate of asymmetric nuclear matter are also calculated with different asymmetryparameters. It is found that the effective neutron mass is larger than theproton one in neutron-rich matter.
